Weavile is fine, I'd recommend he holds Choice Band, since that'll give him that extra boost on his attack, plus with his natural speed he's an excellent Choice Bander, since he can hit and run easily, very few things outrun him, and only really aerodactyl who can be a threat.
Skarmory, switch roar with whirlwind. The moveset works nicely, but whirlwind hits pokemon who have the ability soundproof. I know there's not many, but it just covers all pokemon, instead of about 3 short.
Garchomp is fine, I'm not sure he needs dragon claw, but that's up to you. Personally I'd recommend outrage if you haven't bred him yet, or stone edge if you have. Stone Edge, hits a lot of extra pokemon for super effective, and works well with Earthquake. Good choice on Jolly, I see far too many adamants, that just get destroyed in battling.
Electivire seems to only have 3 moves... Put on earthquake, means you can hit 12/17 types super effective, and with his strength that's excellent.
Blissey is alright, I'd personally take off sing, and put on thunderwave, and maybe take off ice beam and put on shadow ball. Seismic toss can hit everything other than ghosts for 100 damage, so shadow ball will clean up that problem. Thunderwave has better accuracy, and lasts all game rather than on chance until they wake up. I personally prefer the reliability of thunderwave.
Swampert again only has 3 moves and a letter. I assume it's Earthquake, Avalanche, Protect, Waterfall. This itself is fine, however I would recommend stealth rock over protect. Since protect is unreliable, and with his defenses, having a stealth rock on hism would be nice.
I see one major flaw in your team, and that's the complete lack of any special attackers. In competetive battling, if you come across an opponents steelix, then he can pretty much wall your entire team. I would recommend gengar knowing Thunderbolt, Shadow Ball, Sludge Bomb, Hidden power ice/energy ball.
Perhaps something like houndoum could do well as well. Sunny Day, Flamethrower, Solar Beam, Hidden power ice/hidden power psychic. Psychic would add nicely to your team, flamethrower would hit steelix's and other steel pokemon very nicely. HP Ice could hit ground pokemon and dragons, who can give him problems. Sunny day works great with solar beam and flamethrower, giving them both a boost.
Just my suggestions. If you fancy a battle feel free to message me, I'm usually game.
